Buddy of mine just had the both partial knee replacements done in Nov and Dec. Not sure of the rehab difference and ultimate results compared to a total knee, but it looks much faster. He is not in the best CV shape and the inactivity time caused by the surgery has not helped. This is a 6 day, 2000 ft vertical per day, 8-10 miles per day, 50% off trail hike at 10-12,000 ft., over some rugged terrain, in July. He is a pretty tough and determined guy. I am concerned about a lot of things but from what i read, downhills, especially with a pack, are the bugaboo for knee replacements. He needs some overnights starting in May or June to be ready, in my opinion, and I am concerned there is not enough time from surgery to carrying a pack to ultimately being in shape.
Thoughts, experience, suggestions? Thanks, Art
